/* ============================================================================
   theme.css — "Scrap Metal" design system v1 (2026-07-14, Claude Design handoff).

   ONE visual language for every page: near-black canvas (#0E0E10), dark
   surfaces with hairline borders, sharp 2px corners, NO shadows, a single
   rust-red accent (#CD412B) used with intent, and a strict typography split —
   Anton for DISPLAY HEADINGS ONLY (uppercase, line-height .95), Oswald 500/600
   for labels / card titles / buttons / stat numerals, Roboto for body copy.
   Texture: 3% SVG fractal noise on heroes + feature panels, a diagonal hazard
   stripe used once or twice per page max. Motion: mechanical, 150–250ms,
   ease-out only.

   Loaded from base.html right after header_style.css, BEFORE each page's own
   CSS: this file owns the shared vocabulary (tokens, nav, footer, buttons,
   chips, tiles, stat panels, forms, pagination); page CSS keeps only
   page-specific layout.

   ⚠ Don't reintroduce per-page copies of these classes. Tokens first; change
   them here, not downstream. Red is reserved for: primary CTAs, active states,
   hover underlines, the logo. Never body text, backgrounds, or decoration.
